LAMP.

SPECIFICATION forming part of Letters Patent No. 392,822, dated November13, 1888.

Application filed August 17, 1887. Serial No. 247,188. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JAMES FRANK PLAoE, a citizen of the United States,and a resident of Montclair, in the county of Essex and State of NewJersey, haveinvented certain Improve ments in Burners for LiquidHydrocarbons, of which the following is a specification.

My invention relates to that class of burners for lamps and the likewhich employ tubular wicks and which are adapted for burning liquidhydrocarbons; and the object of my invention is to provide for a moreperfect combustion of the oil than is ordinarily attained in burners ofthis general character.

My invention will be fully described hereinafter, and its novel featurescarefully defined in the claims.

The drawing, which serves to illustrate my invention, is a sectionalelevation of a lamp provided with my improvements.

A represents the body or oil-receptacle of an ordinary lamp, in which ismounted an annular wick-tube, K, adapted to receive an or dinary tubularwick, j. The air passes up through the hollow or bore of the wick-tubeto supply the inside of the ring-like flame with air, a centraldraft-tube, D, being provided to lead all of the air thus supplied intoa regenerative distributing-cap, D, which houses the upper end of thetube D. This cap D comprises a cap-plate, e, and a perforated side wall,f. I prefer to enlarge the cap D at the top, so as to extend out overthe wick and to contract it below, as represented; but this is notabsolutely essential. The tube D extends up into the cap nearly to thecap-plate e, and the upper portion, 1', of said tube (which may or maynot form an integral part of said tube) is flared to correspond incontour with the flared portion of the side wall, f, of the cap. Thereis an annular'space or passage, t", between said wall f and the upperportion of tube D, which is housed in the cap. This de vice compels allthe air supplied to the inside of the flame to pass up to the upperportion of the distributing-cap,and thence over the flared top of tubeD, and downward again by way of the annular passage t", exterior to saidtube, from which passage it passes out through the perforations in thewall f to the flame. The heated air is thus supplied uniformly to theflame-wall in fine and evenly-distributed jets. The outside of the flameis also supplied with air in a similar manner, all the air that reachesthe exterior side of the flame being also heated and distributed to theflame.

B is an ordinary draft-chimney, made from glass or other similartransparent material. This chimney is mounted on asupport, g,whichconsists, as herein shown, of a folded plate, with the fold or bightturned upward. The two plies of this folded plate form two perforatedring-like walls or bands, which surround the upper end of the wick-tube,leaving an annular space, 9*, between them. All the air that reaches theflame from the outside must pass through the perforations of the outerband into the space 9*, and thence through the perforations in the innerband to the flame. As these bands 9 become hot, they heat the air on itspassage inward, and they also distribute it evenly to the flame allaround.

To further heat the air before it reaches the flame from outside, ,Iemploy an exterior chimney, O, of glass or other transparent material,said chimney surrounding at its lower part the perforated bands 9, atthe base of which it is provided with a holder, 9. At its upper partthis exterior chimney surrounds the lower part of the draft-chimney B,an annular passage, h, being left or formed between the two chimneys Band C and between the outer chimney and the bands 9, down which the airmust pass to reach the perforations in said bands. The arrows in thefigure indicate the courses of the air-currents on their way to theflame.

I am aware that it is not new to provide burners with double chimneyshaving an annular passage between them for the air to flow through onits way down to the flame, and that it is not new, broadly, to providemeans for heating the air to be supplied to the flame of a burner.Therefore Ido not claim these features.

My burner is especially designed for illuminating purposes; but it mayalso be employed for heating.

Having thus described my invention, I

claim- 1. In a burner for liquid hydrocarbons, the combination, with anannular wick-tube, K, of an air-tube, D, arranged within said wick- IOOtube, through which all the air passes that is supplied to the inside ofthe flame, and a re generative distributing-eap, D, which houses theupper end of said air-tube and has a lateral enlargement at its top thatextends out over the upper margin of the wick-tube, said cap comprisinga cap-p1ate, e, and a perforated wall, 1'', the said tube D extending upinto said cap nearly to plate a and provided with a flared extremity,substantially as shown.

2. In a burner foriiquid hydrocarbons, the combination, with the annularwick-tube K, of the two perforated bands 9, arranged exterior to andsurrounding said wick-tube, inclosing between them an annular space, 9*,the

draft-chimney 13, mounted on the top of said bands 9, and the chimney G,arranged exterior to and surrounding the bands r and the lower part ofthe draft-chimney, said chimney 0 being of such size as to leave anannular airpassag'e, h, between it and the draft-chimney and bands, asset forth.

In witness whereof I have hereunto signed my namoin thepresence of twosubscribing witnesses.
